1. 单目视觉三维重建问题 在前面的文章中,笔者用SIFT提取特征后用radio测试剔除了匹配中异常的特征点,然后根据匹配合格的特征点计算基础矩阵和本征矩阵,对本征矩阵SVD分解来估计和构造透视矩阵,根据透视矩阵和齐次坐标变换后的特征点三角化获得特征点在三维空间中的坐标。 (1)找不到外极线 对于运动范围过大的两幅图像,有可能计算不出外极线。
OpenCV is one of the most common libraries that you need in any computer vision or image processing task. Before applying different filters for image processing or to perform any image-related task, you must know how to read an image, display an image, or write an image....
Now, here is an embarrassing icing on the embarrassing cake. The algorithm implemented in OpenCV is one bySklansky (1982). It happens to be INCORRECT! It is still a popular algorithm and in a vast majority of cases, it produces the right result. This algorithm is implemented in theconvexHu...
